Xamarin Native Xamarin.iOS.Common.targets Error - xamarin.ios

I recieved the following build error for a Xamarin iOS project.
Severity Code Description Project File Line Suppression State
Error AggregateException: One or more errors occurred.
MessagingRemoteException: An error occured on client Build490752 while executing a reply for topic xvs/Build/4.9.0.752/execute-task/AdvisedClient.iOS/a4a40d4002fACTool

The Xamarin.iOS.Common.targets file states clearly not to edit it. What gives?

issues after updating to Xamarin Studio

Could not register the assembly
Error messages that I am getting:
'MonoTouch.Dialog-1': MonoTouch.MonoTouchException: Cannot register two managed types('MonoTouch.Dialog.BaseBooleanImageElement+TextWithImageCellView, MonoTouch.Dialog-1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=84e04ff9cfb79065'
and
'MonoTouch.Dialog.BaseBooleanImageElement+TextWithImageCellView, xxxxx1, Version=0.0.0.0, Culture=neutral, PublicKeyToken=null') with the same native name('MonoTouch_Dialog_BaseBooleanImageElement_TextWithImageCellView').
tried with mtouch arguments --registrar:legacy, not able fix the issue.
You've included both MonoTouch.Dialog-1.dll and MonoTouch.Dialog.dll in your app. Choose one.

Could not compute a complete dependency map for the project

i would like to get rid of this message so build time dramatically decreases (it builds and runs ok).
This warning appears in mtouch.
warning MT3006: Could not compute a complete dependency map for the
project. This will result in slower build times because Xamarin.iOS
can't properly detect what needs to be rebuilt (and what does not need
to be rebuilt). Please review previous warnings for more details.
Test solution: helloworld mvvmcross solution with ios project and pcl (wp8+monotouch+net45+android) + Microsoft HTTP PCL package in pcl only + an async call to HttpClient.GetStringAsync in the pcl.

You must make sure that all the assemblies only reference BCL assemblies that Xamarin.iOS ships.
For example:
warning MT3005: The dependency 'System.Net.Http, Version=1.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' of the assembly 'Com.Catenum.Intouch.Business, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' was not found. Please review the project's references.
Xamarin.iOS does not have a System.Net.Http v1.5.0.0, it has v2.0.5.0 instead (all the Xamarin.iOS base class libraries have version v2.0.5.0, except monotouch.dll itself). The solution is to recompile Com.Catenum.Intouch.Business as a Xamarin.iOS class library (this typically involves creating a new Xamarin.iOS class library project, and link the source files in), which will ensure it contains the correct reference to System.Net.Http.dll.
Note that in Xamarin.iOS 7.0.4 there is a (harmless) bug which causes spurious MT3005/3006 warnings in some cases. This is probably the case for the first warning:
warning MT3005: The dependency 'System.Windows, Version=2.0.5.0, Culture=neutral, PublicKeyToken=7cec85d7bea7798e' of the assembly 'Cirrious.CrossCore, Version=1.0.0.0, Culture=neutral, PublicKeyToken=e16445fd9b451819' was not found. Please review the project's references.
since Xamarin.iOS does contain a System.Windows assembly with that version.

The dependency ''mscorlib, Version=2.0.0.0,...' was not found

i get the following error by compiling my project:
warning MT3005: The dependency 'mscorlib, Version=2.0.0.0,

I've found out that the System dependency of my project uses the version 2.0.5.0 and the ZipSharp uses 2.0.0.0
What should I do?
To fix the warnings you need to get (or build from sources) a version of ZipSharp that is compiled against the BCL (mscorlib.dll, System.dll) that is shipped with Xamarin.iOS (i.e. 2.0.5.0).
Note that those are warnings, not errors, so it might work.

error MT3001: Could not AOT the assembly when during MonoTouch project compilation

I have 2 projects in solution 1. PCL library project (PCL.dll) 2. MonoTouch project
When I'm trying to compile MonoTouch porject I get the following error:
error MT3001: Could not AOT the assembly '../obj/iPhone/Debug/mtouch-cache/Build/PCL.dll'
when I set "link sdk libraries" at MonoTouch project settings I got another error:
MonoTouch Trial version 6.4.0 using framework: /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk error MT2002: Failed to resolve "System.Linq.Expressions.ConstantExpression System.Linq.Expressions.Expression::Constant(System.Object)" reference from "System.Linq.Expressions, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a"
I don't use LINQ and have no references to Syste.Linq.Expressions.

Linking External dll

I am working with Visual Studio 2012. I am externally "Microsoft.Phone.Controls.Toolkit.dll". The project compiles and works fine when I run in debug mode. However gives me the following error message when I try to compile for release:
Warning 1 Could not resolve this reference. Could not locate the assembly "Microsoft.Phone.Controls.Toolkit, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b772ad94eb9ca604, processorArchitecture=MSIL". Check to make sure the assembly exists on disk. If this reference is required by your code, you may get compilation errors. WindowsPhoneNavigationTransitions
How do i solve this issue?
